Capacitor voltage needs ?

I am new to valves, So obviously I do not understand them.
Having said that, I have been handed a preamp to 'update' (yes some of the parts really do need replacement due to eminent failure).
I believe it is capable of 12v output.

My questions are in regards to c2 3uf/200v film cap.

What voltage does it actually need to handle ?
How much frequency response change would it cause if it was changed to a 2.7uf or 3.3uf ?

Thanks 🙂
